Passive Effect
Wild Hunt deals massively (+150%) more damage to Frozen targets.
Standard Skill
Wild Hunt has a "Breath of Snow" gauge in the centre of the screen, which recovers over time when Lyfe isn't using her standard skill.
Using her standard skill cuases Lyfe to launch projeciles forewards, dealing AoE frost damage.
Lyfe regenerates 30 Breath of Snow per second when her standard skill isn't active, and uses 25 per shot when it is active, firing at a rate of 1 shot every 0.25s.
(Thus it uses 100 Breath of Snow per second while active.)
The max is 300 Breath of Snow.
This means it takes Wild Hunt 3 seconds to fully deplete her Breath of Snow, and 10 seconds to fully recover it.
This skill has an S-Energy cost of 5 and a 5 second cooldown, so its dps is entirely limited by Lyfe's Breath of Snow regen rate.
With its second Neuronic, this skill gains extra damage if used when the Breath of Snow gauge is full.
This becomes useful with her Manifestation buffs.
With its first Neuronic, each projectile has a 10% chance to Freeze the target for 3s, with a 15s cd per target.
The isn't the most consistent thing ever, but it does allow Wild Hunt to regularly Freeze enemies.
Given that Lyfe's passive Deiwos effect gives her massively more damage vs Frozen targets, having her regularly freeze enemies is a huge buff to her damage.
Ultimate Skill
Wild Hunt's ultimate skill causes her to deal AoE damage in front of her.
Enemies hit are Frozen for 4s (6s with its first Neuronic).
With its second Neuronic, it her ult hits a Frozen target with less than 5% HP, it takes damage equal to its current HP, basically instakilling it.
Wild Hunt's ult has a very long cooldown of 80s, and a U-Energy cost of 100 (i.e. the default max U-Energy cap).
This means its uptime is low and thus its dps isn't great.
Support Skill
Lyfe damages and Freezes enemies in front of her, and applies a frost DoT for 4s that deals damage very 0.5s.
With ths skills first Neuronic buff, it lasts 10s instead of 4.
The total damage is ok for what it is, and inflicting a control effect (Freeze) is good, but like all main dps operatives you really don't want to be using Wild Hunt as a support at all.
